CAR-AX BOX.

SPECIFICATION forming; part of Letters Patent No. 730,185, dated June 2, 1903.

Application ilecl JuneS, 1901. Serial No. 62,832. (No model.)

citizen of :the United States, residing at Depew, in the county of Erie and State of New York,have invented certain new and useful l Improvements in Oar JournalBoxes, of which the following is a specification.

My invention relates to an improved car journal-box having a cover provided with a groove in which a packing of lead is cast when the cover is fitted on the box, so that the surface of the packingwill conform exactly to the surface Vof. the'box against which it fits; and the object is to form a practically air, oil, dust, and water tight-joint between the cover and box.

The invention also relates to certain other improvements in construction, all of which will be fully and clearly hereinafter described and claimed, reference being had to the accompanying drawings, in which- Figure 1 represents a side elevation of my improved car journal-box and a fragment of a car to which it is bolted, also showing the cover open ingdotted lines. Fig. 2 is a top plan view of the box. Fig. 3 is a section on line a at, Fig. 2. Fig. tis an end elevation of the box with the cover removed. Fig. 5 is a detached view of the cover. Fig. 6 is a fragmentary'section on line b b, Fig. 7. Fig. 7

is a fragmentary section on line c c, Fig. 6.v

Fig. 8 is a fragmentary section on or about line d d, Fig. 5.

In referring to the drawings in detail like numerals designate like parts.

The body of the box 1 has the usual jour- I nal-opening 2 `for the axle and the lugs or ears 3, through which the bolts at are passed to fasten the box to the car 5. (See Fig. 1.) A hinge portion 6 extends upward from the outer portion of the top of the body and has a horizontal opening 7, from which a slot 8 extends diagonally backward through the hinge portion. The edges of the outer opening 9 in the box are exteriorly beveled, as shown at 10, and a cover 11 is provided with anges 12, correspondingly beveled and extending laterally from all of its sides and adapted to iit against said edges. The cover 11 is provided on its inner surface near its upper end with a transverse groove 13, extending throughout froln side to side and of a sufficient depth to permit passage through one of the edge portions of the slot 8. 'An elongated opening 16'is formed in the cover above the groove 13, substantially as shown in Fig. 5, which is slightly longer .than the hinge portion 6 and slightly wider than the thickness of the metal in said perforated hinge portion 6. The' end of the cover beyond the groove 13 is of a curved formation in cross-section, substantially as'show'n in Fig.

1, and the portion 15 exterior to the opening 16. forms a hingepart which fits and turns in 4theopening 7in the hinge portion `6.

The'cover is easily removed from or attached to the body of the box when separate from the car by bringing the reduced portion formed by the groove 13 opposite the slot and then sliding the coverlaterally to the box.

To form a perfect-'fitting and noiseless seat, the flange of the cover is provided with a dovetail groove 17, from which a bell-shaped opening 18 extends to the exterior.

When the cover is in place, molten lead is poured through the opening into the groove to fill the same and forni a packing 19. The

lead shapes itself to the adjacent surface of the box, and thus forms an oil and water tight and practically dust-proof joint'.

A dat spring 2O is rigidly fastened at one end to the cover and has its opposite end ten- 4sioned against the hinge portion 6. The outer surface of the portion 6 is shaped so that it forms a projecting knuckle against which the spring end presses, so that the tendency of the spring is to hold the cover closed with a spring tension.

A recess 21 is formed Vbetween the beveled portion ofthe box and Athe hinge portion 6 to provide a seat for the flange on the rear of the cover. Bythis means beveled anges fit against all parts of and entirely surround the exterior beveled edge of the mouth of the box when the coveris closed upon the box.

The box is attached to the car so that the cover cannot be opened sufcientlyto permit detachment, owing to the car-truck 5, against which the cover abuts when opened to the widest extent, as shown in dotted lines in Fig. 1. locked to the box when in place on the car and cannot be removed or lost.

ICO

B v this means the'cover is One of the great advantages of this construction is that the inclined flanges of the cover are provided with a soft yielding metal surface, which is cast in the dovetail groove when the cover is in place and the flange is against the body, so that it is adapted to fit perfectly against the corresponding inclined top surface of the box. By this means the joint between the beveled surface of the iianges and the side edges of the box is practically water and oil proof when the cover is down.

The packing in this invention is in the flanges of the cover instead of in the bottom of a groove, as in many other journal-boxes, so that the joint is between two surfaces which wedge against each other, and thus securely seal the same,and is not merely formed by seating a ange in a groove containing packing.

I claiml. In a car journal-box, a body having an opening, the outer edges of the walls thereof being beveled, a cover having grooved iianges on its sides fitting over the opening of the body, and softmetal packing cast in the grooves of the iianges, and having its exposed surface conforming throughout With those portions of the beveled outer edges of the box with which it is in contact when the cover is against the body.

2. A car journal-box having a single lug extending upward from the outer end thereof and provided with a horizontal opening and a slot extending from the opening through the lug, and a cover having a transverse groove near its rear extreme provided with a reduced portion sufficiently narrow to move laterally in the slot adapting it to be attached to and detached from the box by lateral movement, there being an elongated openingin the reduced portion through which the lug is adapted to pass, and an outer hinge part adapted to engage in the horizontal opening in the lug, in combination With a car to which the box is to be attached having a stop above the plane of the coverwhen open to the proper joint for detachment from the box, whereby the cover cannot be opened suiiciently to be attached to or detached from the box by lateral movement when the box is fastened to the car.
